摘要

The assessment of urban green space (UGS) ecological and landscape services includes two aspects of ecological environment and landscape perception, which are crucial to sustainable development. Based on the three-dimensional Karst UGS environment, this study evaluates UGS ecological and landscape services using the index evaluation system with multi-dimensional attributes and the TOPSIS method. The results shows that: (1) the distribution of Karst UGS ecosystem service generally shows a “high in the east and low in the west” pattern, while the landscape perception service shows nonlinear; (2) SC has the highest weight, accounting for 20.89%; (3) the proportion of low-quality UGS was 89.63%; and (4) there is significant correlation between ecological benefit indicators. GSA has a significant correlation with the other seven indicators. This evaluation of UGS in South China Karst from ecological, residential, and social perspectives offers insights for global Karst urban management.
